The Siemens SIRIUS 3RV1011-0BA20 is a motor protection circuit breaker sized for a 0.06 kW motor at 400 V AC, with a continuous current rating of 0.2 A and a CLASS 10 trip characteristic. It delivers 100 kA breaking capacity across 240 V through 690 V AC, so it can interrupt high fault currents without upstream coordination concerns in most industrial panels. Phase failure detection is built in, and the main circuit connects via spring-loaded terminals accepting 2x (0.25... 2.5 mm²) solid or 2x (0.25... 1.5 mm²) finely stranded with ferrule.
Mounting and integration
Mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 50022, with zero clearance required at the sides or rear. The 45 mm width and 90 mm height fit standard panel layouts; IP20 on the front face means it is protected against finger contact but not washdown — keep it inside an enclosure. Any mounting position is allowed, and the operating range of -20 to +60 °C covers most indoor industrial environments.
